In the present instance we have illustrated our invention embodied in a Remington machine, model No. 23, equipped with the mechanism of the aforesaid Hart application and in which the devices of the present invention may be readily incorporated without modifying, or materially modifying, other structural features of said machine as it now exists. It should be understood, however, that the invention is not restricted to use in such machines but maybe embodied in typewriting machines generally, whenever found available.

The machine embodying the improvements of the present invention may be used in various kinds of billing operationgwhere two or more work sheets are to be correlated in the machine and printed at a single operation. However, we do not deem it necessary to describe specifically the many different forms of billing operations in which the machine may be used. It is sufficient for an understanding of the present invention to specifically describe one mode of billing that may be successfully carried out with pany, for simultaneously, or at one writing,

making out a bill, making corresponding entries on the ledger sheet carrying the account, and on a record or register sheet which receives the entries written on all of the individual bill and ledger sheets. In the example referred to, the register sheet and its accompanying carbon sheet remain in the machine. The ledger sheet which usually requires but a single cross line entry at a time, say, for the month for which the entry made, may be in the nature of a blank with different vertically ruled columns to be filled in under appropriate printed headings; each cross line of the sheet being ruled ofl horizontally and given over to a different month, and the entire sheet covering a period of anywhere from, say, eighteen to thirty-six months. Means are provided to enable each ledger sheet and its accompanying carbon sheet to be quickly introduced and properly positioned to receive the requisite entries in the line allotted for the month in question without disturbing the previously introduced register sheet. Means also are provided for then quickly entering a bill sheet into the machine in front of the platen, and accurately positioning it in proper correlation with the previously introduced ledger sheet and the printing line. The entries may then be made on the bill sheet and these will be transferred through interposed carbon sheets to the ledger and register sheets. If desired, additional entries may be made on the ledger sheet which are not to appear on the bill or register sheet. .The bill and ledger sheets are then rapidly withdrawn from the machine without disturbing the register sheet, and an other ledger sheet and a bill sheet may then be quickly introducedas before, and so on.

In some instances the Remington bookkeeping machine model No. 23 is equipped with power driven carriage return mechanism such as is disclosed in the patent to Frederick A. Hart No. 1,567,590, dated Dec. 29, 1925. Vic have shown the present invention embodied in such a. machine, but

ing lixedgguide haye; shown only; so much thereof as is nec essarylo arrive at an understanding of the present invention in its embodiment therein.

The i i-nine of the machine is ofthe usual construction and i i i i a top plate 1 carryoppositely grooved to receive crosse r-l'rictionguide rollers 31 These rollers arealso receivedin oppositely groovedcarriage rails int the tront andueacot the carriage said rails being connected with the end bars 5 and 61 o'f the brackets 11 which project rearwardly from andardtixed tothecarriage. In the ma- Chill Q inuvhiclr the present lnventlon 1s shown en'ibo'died the carriage may be re- 'ned by p Wer from a motor 12, as dis cl sed in, said'her einbefore mentioned patent.

In order to prevent work sheets in the machine from extending; back il'OIl'l the marriage and :t'ouling on the tabulator frame 7, and the motor-l2, etc, there is provided a sheet metal protecting; shield or auxiliary paper table 13 which is fixed to the carriage and extends substantially tiroughout the width thereof. This shield extends substantially horizontally fron'rits forward end-where it is fixed to the carriage andprojects rearwardly over the tabulator frame 7, the motor 12, etc. The shield 18 is secured by headed screws 14 to a cross bar 15, secured at its ends byscrews 16 to upright hexagonal posts 17. The posts are tapped to receive the threaded stems of the screws 16, and also to receive/the stemsof headed screws 18 that pass through holesflin the column stop bar and secure the posts 1'? thereto near theends otsaid bar, 7

Any work sheets that may extend rearwardly beyond the carriage, and back beyond'the upper edge of the paper table, will rest on the shield and be prevented thereby from fouling on themotor or the tabulator parts, 7

The platen 19 is carried by the platen frame in the usual manner, said platen frame comprising end plates 20 and QI'united by crossbar The platen lran'ie is connectet to the carriage or truck by links 23 in the usual xnarmer, whicl'r links ordinarily guide the platen frame in its case shitting movementsi The present machine, however, is intended to write only with capital. letters or upper case characters and there is, therepower driven in the ing movements.

The n:

ribbon vibrator mechanism is employed s as to inter-pose the. .ribbon, in the path of )es27 at each actuation of a so much of thisrmechan-iszn is necessary to arrive at a n un how it is cont-rolled in ;acco it c with the present-invention.

lne ribbon vibrator30 is guided for up and down movement on the type guide-31; in the usual manner. The vibrator is operativelyv connected at its lowerend :to, an actuating; arm 32, by which upward motionls given the vibrator at each printingloperation; the arm at this time turning on ap'iyot 33, and being limited in such movement by a stop 34. The frame, carrier, or support'35 by which the arm 32 is carried, issupported on links 36 that ordinarily enable the-frame and the parts carried thereby to shiftjup and down with the platen in its shitt- This ordinarily, is: brought about as lt'ollows: A spring 37 tends to elevate the "frame and the parts carried :ed by a bar 38 fixed to the crossbar elem platen frame an d extending substantially through out the length thereof, Av roller carried by the frame 35 l iearslup against the lower edge 01'? the bar-38, being pressed up against thebar by the spring 37. ()rdinarilya the roller 39 will follow the up and down movements ofthe bar-38 Whenthe platen is shifted to upper and lower case posit-ions and thus cause the. normal position of the vibrator to be shifted accordingly. How ever in the present construction there is no such case shifting; movenunls ot the 'arts, so therefore the parts normally will-be retalned in the 1 positiorn with the roller 39 pressed up against the bar by the spring 37.

in order to give greater access tothe front of the platen tor positioning: other parts at with the outerthis point, as will hereinafter appear, it is desirable at times to lower the ribbon vibrator from its normal position. his is accomplished in accordance with the present invention as follows:

A bracket arm is secured to and projects upward and forward frointhe frame 35, and at its upper end carries an anti-friction roller 41. A bar, plate, or controlling member 42. .which extends substantially throughout the length of the carriage, has its rear edge portion secured, at 43, to a rock shaft 44. This rock shaft is mounted at its ends in bearing openings in the end plates 20 and 21 of the platenframe, and its rocking movement is controlled in a manner to be hereinafter pointed out. The forward edge of theplate 42 is bent down to form a flange 45 that is adapted to coact with the anti-friction roller 41 and move the frame 35 together with the parts carried thereby, or connected therewith, down from the 1 to the Fig. 3 position when the forward edge of the plate 42 is lowered. The effect of this is to lower the ribbon vibrator 30 from its normal Fig. 1 position, to a position such as is represented in 3, thus moving the ribbon vibrator out of an obstructing position where, as the parts are shown herein, it would interfere with the movement of certain parts employed to facilitate the rearward introduction of work sheets from the front of and beneath the platen, as will presently appear.

Coming now to the means for controlling and guiding the work sheets, it will be observed in the first place that there are no paper feed rollers employed beneath the platen, such feed rollers as are employed be ing located above the printing line; leaving the space beneath the platen free for the use of other devices.

There are two curved paper deflectors 46 and 47 employed beneath the platen, one arranged above the other and maintained spaced apart by intermediate spacing members or blocks 48 and 49 located near the ends thereof, as shown in detail in Fig. 1.3. Generally speaking these deflectors beneath the platen conform to the curvature of the latter, or are substantially concentric therewith, and extend substantially throughout the length of the platen. As thus constructed there are two separate channels provided. one of which is the open channel 50 between the two deflectors, and which is bounded at its ends by the separating.members 48 and 49, either or both of which may constitute side guides or for co-operation with a work sheet or sheets introduced into the channel 50. The other separated the deflector 47 terminates in advance of the forward edge of the deflector 46, and that said edge portion has a slight downward curve in cross section. The deflector 47 is continued up at the rear to form an upwardly and rearwardly extending paper table 52, which terminates at 54 at a considerable height above the platen. On. the other hand, the deflector 46 terminates in the rear of the platen at a much lower point and below the top of the platen, where it is bent to form a loop 55 that loosely surrounds a rod 56 fixedly connected at its ends to the end plates 20 and 21 of the platen frame. In this manner the rigidly united deflectors 46 and 47, together with all of the parts carried thereby, are mounted on the rod 56 and have a slight pivotal movement around said rod. The construction is such that the heavier parts connected to the paper deflectors in the rear of the pivot rod 56 cause the forward edge portion of the deflector 46, normally, to be lightly pressed against the platen, or against the interposed sheets R Pt. In this manner the sheets R R are held snugly against the platen and sheets I, L L intended to be in troduced rearwardly into the channel 50 are prevented from entering the channel 51. By moving the upper end of the paper table forward, the forward end portions of the deflectors may be moved downward a limited distance, thus carrying the forward contact edge of the deflector 46 away from the platen, all as provided for in the construction disclosed in the hereinbefore mentioned Hart application.

Certain adjustable work sheet gaging means, or paper end stops, which coact with the bottom edge of a ledger sheet L introduced through the channel 50, are supported on the paper table 52 and contribute to the preponderance of weight back of the pivot rod 56, spoken of above. These devices are the invention of Cloyd E. Burns and are claimed in aseparate application filed by him July 13, 1926, Serial No. 122,239, but are disclosed herein in order to arrive at a better understanding of certain features of the present invention employed in connection therewith. These adjustable end stop devices which coact, in the present example, with the ledger sheet, are constructed as follows:

Upright bars 57 are fixed at 58 to the back of the paper table 52, and extend upward beyond the upper end 54 of the table through openings 53 (Fig. 13) in the upper bent portion thereof. These bars are connected at their upper ends to a cross bar 59 by suitable connecting means. Such connecting means comprise headed bolts 60'and nuts 61. Each associated pair of bolts 60 also pass through openings in a downwardly extending inclined bar 62 to firmly connect the latter to, and support it wholly at its upper end by,

This not only gives additional strength and rigidity to the deflector but facilitates manufacture and enables the deflector to be readily mounted. Thus, a deflector of the requisite length, depending on the length of the carriage employed, may be cut from a long folded strip. In the open ends of the channel formed by the looped portion of the deflector (Fig. 14) are received oppositely directed ears or bent ends 74 which project inwardly from parallel sheet metal arms 7 and 76 and are riveted to the deflector 72. These arms 75 and 76 are pivotally mounted respectively on forwardly projecting arms on the end plates 20 and 21 of the platen frame. The arm 76 carries a fixedly connected sleeve or hub 77, received and adapted to turn on an inwardly extending pivot pin 78 carried by the end plate 21. f} coiled expansion spring 79 surrounds the pivot 78, pressing at one end against a shoulder 80 on the pivot and at its opposite end against the arm 7 6. The power of this spring tends to force said arm 76 and the part-s connected therewith axially of the pivot 7 8, from the dotted to the full line position, for purposes which will presently appear. The arm 75 receives a pivotal support on the shou dered bearing portion 81 of a headed pivot screw 82, received at its threaded end in a supporting stud 83 that is secured to and projects inwardly from the end plate 20. An actuating arm, member or lever 84 has a hub 85 fixed thereto that receives a pivotal bearing on the reduced portion 86 of the pivot screw 82, and is confined against axial movement thereon by the end of the stud 83 and the shouldered portion 81 of the screw. The arm 84 carries a laterally projecting connecting pin 87 riveted thereto and projecting inwardly therefrom. This pin is adapted to be seated in a registeii'lng opening 88 in the arm 75 when the parts are in the full line position shown in Fig. .14. At this time the arms 84 and 7 5 are locked to turn together around the pivot bearings 86 and 81 respectively and to move the deflector 72 from the ineffective, Fig. 1 position, to the effective, Fig. 3 position.

It will be seen that the axial extent of the shouldered or bearing portion 81 of the screw 82 is such that the arm 75 may be shifted independently of the arm 84 from the full to the dotted line position in 14 against the force of the spring 79. When thus moved the arm 75 is disconnected from the pin 87 and from the actuating mechanism for the deflector 72. The latter with its supporting arms 75 and 76 is then free to drop or turn forward anc downward from the substantially horizontally disposed full line position, shown in Fig. 1, to the sub stantially vertically disposed dotted line v96 fixed thereto.

position. This is to give more ready access to parts arranged below the deflector 7 2 and between it and the platen, and is available more particularly to enable the ribbon 30 to be readily threaded through the ribbon vibrator 30, etc.

Ordinarily, as when the machine is in use, the deflector 72 is maintained in the full line Fig. 14 position by the spring 79, where it remains connected to the actuating arm 84. This arm is connected and actuated, in the present instance, as follows; it being understood that the deflector normally occupies the ineffective, full line position shown in Fig. 1. The outer end of the rivet which carries the pin 87 14) is headed at 89, and has a shouldered bearing 90 for pivotal connection to the rear end of a link 91. As best seen in Fig. 6, the forward end of the link 91 is pivoted at 92 to the lower arm 93 of a lever 94 of the first order, pivoted to the carriage and having an upper arm 95. As shown in Fig. 7, the lever 94 has a hub This hub turns on a fixed pivot rod 97 supported at its ends in fixed bracket arms 98 and 99 secured to the carriage. The end of the pivot rod 97 which is supported in the bracket arm 98 is slabbedoff at 100, where it is received in a correspondingly shaped opening in said bracket arm to hold the rod against turning; a screw 101 holding the rod on the bracket arm. The upper arm of the lever is pivoted at 102 to a rcarwardly extending link 103, which in turn is pivoted at its rear end, at 104, to a curved lever or crank arm 105. This arm at its upper end terminates in a finger piece 105, by which it and the parts connected therewith may be actuated. As best shown in Fig. 5, the lower end of the crank arm 105 is provided with a hub 106 fixed to the rock shaft 44 which, as hcreinbefore indicated, extends across the carriage and is supported at its ends in bearii'igs in the end plates 20 and 21. As shown in Figs. 5 and 6, the left hand end of the shaft 44 extends beyond its bearing and is slabbed-ofi' at 107, for recep- Lion in a corresponding opening in a crank arn'i 108 having a laterally extending projection or lug 109. This arm is secured in place on the shaft 44 by a nut 110 threaded onto the left-hand free end thereof. The lug 109 is notched in its forward edge to receive the free end of a wire spring 111. This spring is coiled around a pin 112 and anchored at its opposite end on a screw 113; the pin 112 and screw 113 projecting outwardly from the end plate 20 of the platen frame. The force of the spring 111 is exerted to return the rock shaft 44 and the parts connected therewith to normal position, shown in Fig. 1, where they are arrested by an inwardly projecting lug 105 on the arm 105 coacting with the face of the platen near the left-hand end thereof.-

ures that this shifting of the deflector 72 carries it from the full line 1 position. where it is out of the path of the types 27, to the Fig. 3 position, where it is interposed in the path of said types and crosses the printing line. This shifting of the deflector 72 changes its angular position, as well as effecting a bodily movement thereof, so that when it reaches the Figs. 3 and 5 position it will overlap the front edge of the deflector 47 and practically form a continuation of the channel 50. With the parts disposed in this position, a work sheet L may be readily introduced from the front of the platen and shifted rearwardly beneath the latter through the channels 50 and 63 until the bottom edges of the work sheet reaches the end stop 65 or the stops 71, as the case may be. Assuming that the bar 66 has been previously adjusted. to the proper position, the work sheet L will be properly positioned to receive a line of imprints on the proper cross-line thereof after the feed rollers, to be hereinafter described, are rendered effective to clamp the sheet against the platen. When the finger piece 105 is released by the operator the various parts referred to will he returned to normal Fig. 1 position by the springs 126, 111 and 37.

It will be seen that the movement of the end stops 120 under control of the key 128 is effected independently of the movement of said stops automatically under control of the finger piece 105 It also may here be pointed out that the movement of the parts described above under control of the finger piece 105 is effected independently of an automatic shifting of said parts by a shift-.

ing operation of certain of the paper feed rollers, as will presently appear.

lVe will now describe the construction and arrangement of the form of paper feed roller mechanism disclosed in said Hart application and which is used in conjunction with the devices of our invention, as well as the means whereby a shifting of certain of said feed rollers automatically brings about a shifting of other of the parts hereinbefore described.

Referring more particularly to Figs. 1, 2 and 15, it will be seen that a cross bar or pivot rod 133 extends throughout the length of the carriage in the rear of the paper table 52, and is secured and held against turning movement at its ends to the end plates20 and 21 of the platen frame by screws 134. Loosely supported on the left hand end portion of the rod 133 is an elongated hub or hearing sleeve 135 of a forwardly extending supporting arm 136 which is fixed to the hub. A spacing washer 136 maintains the arm 136 separated from the end plate 20. A coiled spring 137 surrounds the hub 135 and rod 133 and is fixed at one end to a collar 138 on the rod 133.- Said collar is held in position on the rod by a set screw 139. The other end of said spring is connected to the supporting arm 136, so that the force of the spring is exerted to move said arm downward around the pivot rod. An adjustment of the collar 138 to different set positions around the pivot rod 133 is effective to increase or decrease the force of the spring 13'? on the arm 136, depending on the adjustment of the collar in one direction or the other around said rod, thereby giving an individual tension adjustment for said arm. The arm 136 extends forward over the platen and is provided with a bearing opening 140 that receives the reduced end 141 of the cross bar 142 on which paper feed rollers 143 are mounted to turn. A shouldered headed screw 142 is threaded into a tapped opening in the left-hand end of the rod 142 to prevent a disconnection of the rod from its arm 136. It will be seen from Fig. 15 that the head of the screw 142 does not bind against the side of the arm 136. The opening 140 in which the reduced end of the rod 142 is received is large enough to enable the rod 142 to assume different angular relations to the arm 136, for purposes which will presently appear. The manner of mounting the arm 136, individually adjusting its spring 137, and connecting said arm to one end of the roller supporting rod 142, etc., is duplicated at the other end of said rod. Corresponding reference numerals will therefore be used to designate the corresponding parts at the other end of the rod. The rather loose mounting of the rollor bearing rod 142 in the bearings 140 in the supporting arms 136 enables said rod to change its angular relation to said arms so that it may assume a position out of exact parallelism with the axis of the platen shaft. This construction enables each spring 137 to apply its force individually to the associated end of the roller carrying rod 142, and to the roller 143 nearest said end, and effect an accurate feed of the work sheet R and companion carbon sheet K under varying conditions of use, and cause a substantially equal pressure to be exerted by said rollers, even though a greater thickness of paper be fed under one roller than under the other.

Suitable means are shown to enable each feed roller 143 to be adjusted to different positions along the shaft or rod 142 to ac cord with the width of the work sheet R, and corresponding carbon sheet R. with which the feed rollers 143 coact. preferably at and near the margins thereof. Thus, as seen in Fig. 15, a small coiled spring 144 surrounds the shaft 142 and has a frictiontight binding action thereon, and is contained loosely within a chamber 145 in the bearing; member 146 of the companion rubber covered feed rollers 143. The spring retains the roller in the position which it is adjusted along the rod 142, while allowing the roller to turn freely. I

By swinging the rod 1 12 and arms 136 up ward and rearward away from the platen and around the pivot rod 133, the leading edges of the sheets and it may be readily ii'ltroduced beneath the feed rollers 14-3. The operator then releases the parts and said feed rollers will press the sheets R and R against the platen, to the exclusion of all other sheets introduced in. the machine, as indicated in Figs. 6 and 10.

In order to accurately iosition the sheets 1% and R widthwise in the carriage, we have provided an adjustable side edge gage 14.? with which the left-hand edges of said sheets may be brought into register, as shown in 2. From an inspection of Figs. 1 and 2 it will be seen that the inner contact taco oi"? the blade-lilac member or gage 1 1? extends in a plane at right angles to the axis of the platen. Said member is carried by a hub 148 mounted on and adjustable along l'he roller carrying}; rod lei). A. thumb screw 1 19 is received in a tapped opening in the hub 148 and bears at its inner end against the rod1 l2 to hold the gage in i is adjusted position.

in addition to the paper feed rollers 143 there is employed, as in the construction disclosed in said llart application, one or more sets of feed rollers depending on the use of: the machine as a two-sheet biller or for more than two work sheets. The construc tion .in the present instance is shown and EJl WCll'lCZEllY described in one example of its use as a threc-sheet billcr and consequently we have illustrated two additional sets of paper feed rollers 150 and 151. These rollers are shown arranged above the print in o; line and are in the nature of two sets of margin feed rollers located in axial alignment forward of the feed rollers 143. The teed rollers 151 are more widely separated than the rollers 150, and are intended to co operate only with the wider ledger sheet. L in the cxan'n ile shown, whereas the rollers 150 coact, in the OKillTlPlOSllOYVU, with the narrower bill sheet I. One or more sets of these rollers may be employed dependin on the remiircments, and they may be mounted in any suitable manner to attain the ends in view. its shown in the prr-vsent instance, those paper teed rollers are mminted for in dividual adjustment longitudinally of the platen; they are arranged so that the rollers of each set or pair may be shifted in unison into and out of contact with the platen or the work sheet with which they coact; they are arranged so that the rollers of either set may be shifted in unison independently of the rollers oi: the other set, or the rollers of both sets may be shifted in unison at a single .operatioi'i.

Tle construction also includes means whereby the parts hereinbefore described, such as the ribbon vibrator, the deflector 72, the line indicator 118, end stops 120, etc. are automatically controlled by the shifting of one ot the sets (151) of feed rollers (150 and 151) into and out of eli'ective position, all of which will hereinafter more clearly appear.

in the present instance each of the feed rel ers .150 or 151 is pivotally supported in a yoke-like carrying; member 152, 152, 152 or 152 pivotally mounted on the pivot rod 97, hereinbeiore described, to swing thereon and thus carry the companion "feed roller into and out of effective position. Suitable individual detcnt or holding mechanism is employed to hold each roller in either of such positions and cause the roller to bear, with a spring pressure, against the worlr sheet when the roller is in effective position.

The detent mechanism in question is in each case similar to that disclosed on a large scale in Fig. 7, from which it will be seen that collar surrounds the pivot rod 97 intcrn'iedinte the arms of the yoke and is secured to the rod by a set screw 1. An adjustn'ient oi? the collar 153 along the pivot I rod with the yoke determines'the position of the companion feed rollerlongitudinally ot the platen, and when the set screw 15 1 is tightened axial movementot the collar and its conmanion yoke'is prevented without intet ring with the pivotal movement of the yolie. A follower 155 is slotted at 156 on opposite sides thereof to receive the pivots 157 of a small metal detcnt roller 158. The pivots 157 slide as well as turn in bearing slots 159 in the arms of the associated yoke. A learli spring 160 is attached intermediate its ends, at 1131, to the follower 155, whereas the outer free ends of the spring bear against the end walls 01 the bearing, slots 159. From an inspection of Fig. 1, it will be un-- derstood that the lower rear side of each collar 153 is slabbed ol at 162 forming an inclined contact face with which the companion detent roller 158 coacts when the associated teed roller is in effective position. This causes the companion spring 160 to exert its individual torcc with considerable pressure on the associated teed roller. i l hen, however, the yolre is swung up to release the teed roller the detent roller will bear.

againstthe cylindrica periphery of the collar 153, or in some cases in a notch or groove 153 or 153 formed therein to retain the yoke in the definite predetermined position to which it may be shifted and resist the reaction of certain returning springs as will presently appear. The detent mechanism described above is substantially the same for each. of the teed rollers 150 and 151 except, as indicated above, that in some instances, as for the left hand yoke 152, retaining grooves 153 and 153 are provided r set.

in collar 153 for cooperation with the roller detent 158. Therefore, the same reference characters are employed to designate the ditlierent detent devices. The yoke of each feed roller 150 and 151 is much the same except for the yoke 152". This yoke for the. right hand roller 151. may have its side arms brought together and united at 163 as shown in Fig. 1. This is in order to give greater visibility to the right hand exposed margin of the worksheet L.

in order that each companion pair of these teed rollers 150 and 151 may be shifted into and out of effective position in unison and by a single operation without, nevertheless, impairing the individual spring pressure of the feed rollers on the platen there is provided in the construction the following described mea'ns Referring more specifically to Figs. 1, 16 and" 17 it will be seen that the cross bar of each'yoke or feed roller carrier is provioed with a forwardly projecting headed pin A sheet metal, slightly flexible or resilient, connecting bar 165 is bifurcated or slotted atits ends, as indicated at 166, to receive the stems of the pins 164 on the yokes of the companion pair oi -teed rollers 150 or 151. The end yokes'152 and 152 extend further forward than the intermediate ones, 152 and 152 so that one set of yokes, and the connecting bar 165 therefor, will not interfere with the pivotal movement of the yokes and bar of the other set. It will be understood that the bars 165 may be readily connected to or detached from their respecti e carriers'or yokes, and that bars of diiii'ercnt lengths may be employed, depending on the adjustment of the yokes along the pivot rod 97, or the distance that the rollers of each pair are to be maintained spaced apart on the pivot rod. In Figs. 16 and 11" there is illustrated different relative adjustments of the feed rollers and yokcs, the connecting bars 165 in Fig. 17 being shorter tl, an the corresponding bars in Fig. '16.

The left hand yoke 152 is provider vith an upwardly extending arm 167 which torminates in a laterally projecting finger piece 168', as bestshown in Figs'l and 2. A corresponding" arm 169 and'finger piece 170 is fixed on the left hand yoke 152 of the other As'shown in Fig. 2, the arms 161' and 169 are secured on adjacent arms of the two lett'hand yokes 152, 152 and the two linger piece; 168 and 170 project outwardly away from each" other. This permits, when desired, an adjustment of the two lett yokes in closerelationship. Such an adjustment is not always necessary or desired, and where the two lefthand rollers are to be maintained'more widely separated, as shown in Fig. 1', then thefinger pieces may be es;- tended towards each other, as indicated at 168* and. 170 in Fig. 1 In either event,

however, the finger pieces are arranged in such close relationship, one to the other, that they may be sin'uiltancously grasped by one hand of the operator, if eesired. It is, therefore, easy to turn both yokes to which the finger pieces are connected to an upright position, carrying the companion feed rollers to ineffective position and transmitting motion through the connecting bars 165 to the other yokes, and thus effect a simultaneous shifting 01'' all four feed rollers 150 and 151 away from the platen. On the other hand, a shifting 01 the finger piece 168 merely results in shifting both feed rollers 150, and a shifting of the finger piece 170 results in a shifting of both feed rollers 151 independently of the teed rollers 150. The slight resilien y "a each of the bars 165, while not interfering with the independent Spring aressure applied to each of the feed rollers 150, 151, by its spring160, nevertheless causes both feed rollers operatively connected by each bar 165 to be thrown off together, or substantially in unison.

The locking groove 153 in which the associated detent roller 158 is seat-ed when the yoke is in the throwirofl' upright posi- L044 tion more effectively holds said yoke and the parts automatically controlled thereby, in their actuated positions and against the reaction ot the returning springs 3'7, 111 and 126, as will presently more clearly appear. On the other hand, the locking groove 153", and associated detent roller, hold the yoke 152 and the feed rollers 151 controlled thereby in the intermediate 8 position and as shown in dotted lines in Fig. 1

From an inspection of Figs. 1, 3 and 8 it will be seen that the inner arm of the yoke 152 carries a depending lettdiand side edge gage 171, the plane or which is at right angles to 11 e axisot' the platen. Vv'hen the parts are in and near the normal )JOI-I-ZltlOZl, as shown in Fig. 1, the edge 172 of this gage lies close to the platen, and the gage will coactwith the left hand side edges of the work sheet 1 and the companion carbon sheet L, as indicated in Fig. 2. This providei means for accurately positioning those she lengthwise ot' the platen and in proper relat on to other sheets in the machine.

The control oi the deflector T2, line indicator 118, ribbon vibrator 30, stops 120 etc I is automatically etl'ected by a shifting mov ment of certain of the above mentioned feed rol rs by the following means: Referring particularly to Figs. 1 and git will be seen that the actuating link 103 carries an upstalding ear 1'73 from which an inwardly extending pin 1'14 projects. This pin overlies and extends in the path of the left hand arm of the yoke 152 said yoke is moved c from the normal, full line Fig. 1 position,

to the Fig.3 position to release the feedlrolh ers 151. There is a lost-'motlon' of said arm .ll l

before the pin is picked up, for Tpurposes which will presently appear. :lowever, when the arm in question reaches the pin the latter will continue its movement with the arm, shifting the link 103 and the parts connected therewith from the Fig. 1 to the Fig. 3 position. The effect of automatically actuating the link 103 in this manner is the same as operating the finger piece 105 to the limit of its operating movement. This, as previously described, results in lowering the ribbon vibrator, in shifting the end stops 120 to inefl'ective position, in moving the line indicator to nonindicating position and in moving the deflector 72 to effective position, all as shown in Fig. 3. The parts will be held in such positions under the action of the companion spring pressed roller detent 158 in the groove 153, and against the reaction of the springs 37, 111 and 126, until the margin feed roller 151 are again returned by hand to effective position. The parts in question will then be returned to their normal positions disclosed in Fig. 1 by their respective springs 37, 111 and 126.

lVhile, as has neviouEdy been pointed out, the machine may be used dili'erently under different conditions, we will continue the assumption of a condition of use hereinbetore pointed out, in which a record or register sheet R, a carbon sheet R therefor, a ledger sheet L, a carbon sheet L therefor, and a bill sheet I, are employed to be simultaneously written on, with possible additions made directly in the right-hand margin of the sheet L only. In some instances a pro tecting sheet (not shown) is employed in front of the carbon sheet R, but this is not absolutely necessary and is ignored in the present instance. Assuming that the margin feed rollers 150 and 151 are in the upright ineli'ective position, the record sheet it and its carbon sheet 11 of the same size (placed with its transfer face next to the record sheet) are first introduced together from the rear of the platen through the channel. 51. These sheets are positioned widthwise by bringing the left hand side edges of said sheets against the adjustable side edge gage 1 17, and their leading ends are inserted beneath the feed rollers 143 which alone contact directly with the sheet R. The positions oi the parts at this time are diagrammatically illustrated in Fig. 8. ln thus introducing thesheets It and R, they may be fed forward or back with the aid of the platen 19 and feed rollers 143 and it necessary properly adjusted with reference to the printing line. If desired, the line indicator 118 may be used in aiding in the adjustment of these sheets 'or any sheets with which the rollers 1413. may be' used to coact. In order that the line indicator may be temporarily used at this time, the

finger piece 170 is employed to move the -feed rollers 151 down to theposition indicated in Fig. 8* where they are retained free from the platen by the associated detent 15S seating itself in the locking groove 153 as indicated. By reason oithe lost motion between the feed roller carrier or yoke 152 and the pin 174 this is the point where in the releasing motion of said carrier the pin 17 1- is picked up. It follows, therefore, that at this time, the line indicator 118, the deilec tor 72, the stops 120 and the ribbon vibrator are all in their normal positions, shown in Fig. 8 with the line indicator in position for use in front of the sheets R R.

Next the ledger sheet L is introduced rearwardly through the channel 50, but before doing this the feed rollers ,151 are returned to the Fig. 8 position, th reby automatically restoring the deflector 72 and other parts mentioned above to the Fig. 8 position, leaving the channel open and the parts positioned to readily receive the backwardly ii'itroduced ledger sheet. As the ledger sheet then inserted backwardly it will be guided up in the rear of the platen between the parallel bars 57 and 62, and with the left-hand side edge of the sheet against the side wall 18 ot the channel 50, the sheet will be accurately positioned widthwise with reference to the platen and the previously introduced register sheet It and its carbon sheet R. Then by moving the rollers 151 down to Fig. 8 position the line indicator may be rendered ei'iective to obtain initially the proper adjustment of the ledger sheet L in the line space direction. This is attained with the aid of the line indicator 118 by registering, say, the line dividing the cross column from the printed headings with the line indicator, to write below said indicator in the first or January cross column.

The margin feed rollers 151 are turned down into effective position to coact with the marginal portions of the sheet L, the parts at this time being disposed. as indicated in F 9. The end stop isthen adjusted down to a position where it will coact with the bottom edge or the ledger sheet, as shown in. Fig. 9. All succeeding ledger sheets L introduced into the machine during, say, the

same month, may then be quickly hnd accurately positioned in a line feed direction with the aid of the end stop 65 and without using the line indicator. A single adjustment of the latter in the manner described for the next month will suiiice for all of the ledger sheet entries to be made in that month.

Now in introducing a bill sheet I, which is usually of considerably less length than the record and ledger sheets, a carbon sheet L of the same length and width as the bill sheet may be introduced with the latter. That is true unless the bill sheet has a carbonized back, in which instance no carbon sheet L is required.

Vith the sheets R, R and L held in position by their respective feed rollers 143 and 151, as shown in Fig. 6, the bill sheet I and carbon sheet L may be readily introduced downwardly and rearwardly from in front of the platen into the channel 50. At this time the parts are in the position indicated in Fig. 6, being temporarily moved to and held in such position by actuating the linger piece 105 with one hand, while introducing the sheets I and L into the channel 50 with the other hand. From the position of the parts indicated in this figure itwill be seen that the ribbon vibrator has been lowered from its normal position shown in Fig. 1, that the line indicator 118 has been moved out of the way to an ineffective position, and that the deflector 72 has been moved to an effective position where it will aid in effectively directing the lower ends of the sheets I and L into the channel 50. After introducingthe work sheets into the channel, as indicated in Fig. 6, and releasing the finger piece 105 the parts will return to normal position, as shown in Fig. 10, positioning the end stops 1:20 in the effective position and thus enabling the said sheets I and L to be adjusted against said stops for accurately determining the proper posit-ion of the sheets in the line feed direction. In order to attain the proper wiothwise positioning of the sheets I and L they may be adjusted to contact with the side edge gage 171, since at this time the rollers 151 are in the Fig. 6 position where said gage is effective. The feed rollers 150 are then moved down to effective position, clamping the sheets I and L to the platen, as shown in Fig. 10.

The machine is now in condition to write the bill, and a manifold copy thereof will The act of throwing the feed rollers 150 and.

151 to upright position not only frees the worl: sheets as described, but also results in moving the end stops 120, the ribbon vibrator 30 and the deflector 72 to the positions indicated in Fig. 3, thereby enabling the sheets, I, L and L to be readily with drawn, leaving the sheets R and R" in the machine. The machine is conditioned to receive first newled'ger sheet L and then a new bill sneet I, with an accompanying carbon sheet L, in the manner hereinbefore indicated, and so on as successive bills are written.

It will be understood that in returning the carriage after the last line on a bill written, the platen will be automatically line spaced, which will feet the record sheet ll and companion carbon sheet It forward one space re 7 to receive the manifold copy of the nor-1t bill entered on the record sheet.

ll hen entries for the next month are to be made the first ledger sheet is positioned with the aid of the li: e i. dicator as previously pointed'ont. The end stop 65 is then low ered to contact with the bottom end of the adjusted ledger sheet, and is secured in that position. In all subsequent introd ctions of ledger sheets during that month they may be quickly and accurately positioned with the aid of the end stop 65 (or the stops 71 as the case may be) and side gage 4:8 with the assurance that the bills copied on each ledger sheet through the carbon sheet L will be positioned in the proper blank or space there-- for on the ledger sheet.

We have l'iereinbefore indicated that the present machine is capable o a very wide range of use, and may be employed with or without slight change in almost any character of billing or like work wherein two 01' more sheets are employed, and where one or more work sheets are introduced into and removed from the machine, while another or other sheets are retained in the machine and a certain correlation is required between the sheet or sheets retained in the machine and those introduced therein from time to time.

For example, let it be supposed that the machine is to be used as a check writing machine, in which a copy is to l e made of all checks as they are written. In this event the checks only would be rearwardly introduced into the channel 50. It would be unneces sary in this event to automatically actuate the end stops 120. This might be readily provided for by removing the arm 127 or adjusting it on the shaft to a position where it would not be actuated by the arm 105, in whichevcnt the end. stops 120 would be constantly springme sed to operative position and remain there always ready to coact with the bottom edges of the checks o properly position them, assuming the location of the stops 120 to be a proper one this purpose. Gr, on the other hand, the arm 127 might be allowed to remain on the shaft as shown, and merely advance the end stops 71 to some such position as that indicated in FlP. 12, and permit them to rema n in such position indefinitely. The record of the checks written would be manifolded through the carbon sheet it to the r. sheet R, both of which latter sheets are
